Can anyone tell me roughly what percentage a student will need to pass the Bexley 11+?

It is difficult to tell - becuase it depends on the students; I think last year was 78 %

On the school information page of this site it states '214 is the selective score. There are 786 places available in all four schools . The top 180 children with highest scores are guaranteed a place at their preferred school. The highest possible score is 280'. Thus 214 is 76%. That of course is an oversimplification as different weighting is given to different parts of the paper and the score is standardised so September borns will typically need to score a bit better than August borns. I also don't know if they change the pass mark like they do in Kent for example depending on how many sit the test and how easy/hard the cohort found the test.

Please...

A standardised score of 214 is not 76%! Or at least, it might be. Or 90% (unlikely, admittedly). Or 60%. It depends on the mean raw score and the standard deviation etc. What it isn't, though, is '214 / 280 = 76%'.

Search Stroller's posts for a good explanation - with diagrams - of what standardised scores represent. I've even had a go or two myself (admittedly without the diagrams) :) . What a standardised score tells you is what proportion of candidates, not raw marks, lie above and below it.

Exactly Toadmum, hence I said my calculation was an oversimplification, but I was trying to explain how some people get to believe in such percentages.

For a cem test a score of 214 is equivalent to APRROXIMATELY 55%. You tend not to need 70%+ to gain a GS place in a cem test. Remember in some places the average maths score is only 25%! Obviously super selectives and you will need 65-70%.
Check out vza's post.

Re vza; sd score= (raw score% + 50.9) / 0.9864 - per paper
This is a guide only but gives you a fairly clear indication.
